2 Claims.

'10 thereto a tag bearing his number so that he can be given credit for his work.

These tags are sometimes merely suspended on hooks carried by a side Wall of the car and l are often accidentally displaced.

It is an object of the invention to provide a device whereby the check or tag may be secured to the side of the car against accidental displacement, and I aim to provide a device of this character which is economical both in construction and in operation.

The invention together with, its objects and advantages will be best understood from a study of the following description taken in connection with the accompanying drawingswherein:

Figure 1 is a side elevational view illustrating the application of the invention to a mine car.

Figure 2 is a sectional view taken substantially on the line 2-2 of Figure 1.

Figure 3 is a View similar to Figure 2 with the parts rotated about forty five degrees and showing the manner for releasing the tag or card.

Figure 4 is a perspective view of one of the plates of the device.

Figure 5 is a similar view of the complemental plate.

Figure 6 is a perspective view of the tag or card, and

Figure 7 is a sectional View taken substantially on the line '7--7 of Figure 2.

Referring to the drawings by reference numerals it will be. seen that 5 indicates generally a mine car of conventional construction, the same in the present instance being illustrated as of the dump type. The card or tag usually used by a miner and carrying informative 'indicia, such as the number of the miner and the like is indicated by the reference numeral 6 and in the present form of the invention is rectangular in shape and is provided at one end with an aperture 7.

The improved device for securing the tag 6 to one side of the car is indicated by the reference numeral 8 and includes a pair of complemental plates 9 and. 10. The plates 9 and 10 may be formed of any suitable material and are of any desirable shape. The plate 9 is adapted to be disposed against the outer face of the wall 5a of the car and is provided on the side thereof opposite to the wall 5a with a vertical slot or groove 10 that gradually increases in depth as it apdo proaches the upper end where it merges into a pocket 12.

The plate 10 is adapted to be disposed in juxtaposition to the plate 9 and these plates are secured on the side Wall of the car through the 055 medium of bolts or other suitable fastening devices l3, apertures 14 being provided in the plates for accommodating these bolts.

The plate 10 is provided in the face thereof confronting the plate 9 with a substantially rectangular recess 15 adapted to accommodate the tag 6, and within the confines of the recess 15 the plate 10 is also provided with a groove 16 that mates with the groove or slot 11.

Operating within the pocket 12 and the chani3 the apertured end of the tag is inserted up- 36,

wardly into the groove 15 between the plates 9 and 10 forcing the ball 17 into the pocket as shown in Figure 3, the upper edge of the plate 6 continuing upwardly beyond the pocket to engage the inner end of the groove 15 thus alining 35 the aperture 7 with the pocket 12. The body of the car may then be swung from the position suggested in Figure 3 to the position suggested in Figure 2. This will of course cause the ball 17 to pass from the pocket and into the opening 9Q '7 and to move with the tag 6 downwardly to the position shown in Figure 2. In this connection it will be noted that the ball 17 fits snugly in the lower end of the channel formed by the mating grooves 11 and 16, and engaging in the aperture 7 will retain the tag 6 from becoming accidentally displaced.

To remove the card the operation is exactly reverse to that above described with reference to the securing of the card in position.

Having thus described my invention, what I claim as new is:

1. In a device of the character described a pair of complemental plates secured together, one of said plates being provided on theface thereof confronting the other plate with a recess designed to receive a card passed between the confronting faces of the plates, the first named plate within the confines of said recess being provided with a vertical groove and the complemental plate being also provided with a groove regis- 1 10.

tering with the first named groove and merging at its upper end into a pocket, and a ball operating in said pocket and movable toward and away from the pocket within the mating grooves, and a card being provided with an aperture in one end to accommodate the ball in a manner to releasably retain the card in position between said plates.

2. A tag'holder for mine cars comprising a pair of complemental plates secured in superimposed relation and adapted to be mounted on one wall of the mine car, one of said plates being provided with a groove in the face thereof confronting the other plate so as to permit an end of a card to be passed upwardly between said plates, said plates in the confronting faces thereof, and within the confines of said groove being provided with channels to accommodate a ball, a ball operating in said channels, the channel in the second named plate gradually increasing in depth as it approaches its upper end where it merges into a pocket for receiving the ball, and a card having an end adapted to be passe-d upwardly between said plates and provided in said end with an aperture adapted to register with the pocket for initially receiving the ball, and to be retained in suspension by said ball when the latter is in the lower end of said channels.
